Sudden bruising on all my fingers/fingertips?

I recently returned home from dining out and noticed that when I came home I suddenly had a sharp frontal headache, stomach discomfort with a severe diarrhea episode. Upon leaving the bathroom, I noticed that ALL of the fingers on only my right hand had begun to immediately bruise in spots on both the front and back and had swelled up quite a bit.

I really don't feel any pain on my fingers, and I don't recall any sort of sudden trauma to my hand recently, but I've never experienced anything like this before. I tried doing some research to see if bruising could be related to food allergies and found no connection.

I'm putting a cold compress on my fingers and I took a benadryl to hopefully help with the swelling, but I don't know if I should seek immediate medical attention or just play it by ear. Anyone know what would cause something so suddenly?

Hi there, the sudden bruising and swelling probably suggests that you are deficient in Vitamin C. You should take supplements.
I strongly advise you take enough rest, however, to be on the safer side,see a doctor.
Take care.
